Confusion regarding different multiplications

I’m confused as to the different multiplication styles used in the course. There’s Matrix multiplication , elementwise multiplication and maybe some i didn’t catch. Could someone pls clarify what types are used because Prof Ng’s Notations are getting mixed up in my head​:sweat_smile:
